摘要：

摘要：介绍了2台不同参数的燃气-蒸汽联合循环机组余热锅炉蒸汽管路的吹洗过程，吹管过程分析比较表明：燃气轮机带一定负荷能够为余热锅炉蒸汽管路吹洗提供更高的吹洗蒸汽参数，缩短吹洗时间，节省除盐水；低压吹洗管路独立布置可以解决联合循环余热锅炉吹管过程中高、低压蒸汽系统相互影响的问题。吹管参数的选取可以为同类型机组提供借鉴。

Abstract:

Abstract:The steam pipe blowing processes for HRSG of two gassteam combined cycle units with different parameters were introduced and analyzed. Some conclusions were obtained from the analysis are as below. When the gas turbine runs with certain load, it can provide blowing steam with high parameters, and the duration of pipe blowing and the consumption of desalting water can be reduced correspondingly. To arrange the lowpressure steam blowing pipe separately is useful to avoid interaction effect between the highpressure steam system and the lowpressure steam system of HRSG in combined cycle system.The selection of pipe blowing parameters in this paper can be used as reference for similar units.

Key words: Keywords:gassteam combined cycle unit, HRSG (heat recover steam generator), steam pipe, blowing
